Here's a view of the construct from below. The grey blocks are Basalt,the majority of it being Weathered Bricks,though I do have a band of Encased Bricks at every floor; Cells have it at ankle level,while Darkrooms have it at floor level. The blue blocks are Factory Blocks,chiselled into Blue Circuit texture,with the final visible block type here being the ME Controller variant of the Futura Block.
Here's a view into one of the Cells,this one for Wither Skeletons. That central pillar contains a Mob Duplicator in the middle,with ME Controller Futura Blocks on top,with Covers of the same down below; A Signalum-Plated Fluiduct feeds the Duplicator,and a Redstone Relay is also there. The Lever that controls this is to my right. The floor is covered in Vector Plates,and that device to the right in there is a Mob Masher,loaded up with ten of each for the following; Sharpness,Luck,Smite,and Beheading. Gotta get those drops! The doorway is made of Obsidian; Large Pillars form the sides,with Shiny Panels capping them,and normal Panels across the top. The 3*3 opening is covered by Dark Ineffable Glass. The beautiful floor that's covered up by the necessary Vector Plates is four quadrants of Primal Voidstone,the Dent texture,with the quadrants defined by a cross of Blue Circuit Factory Blocks. Every single Cell is built like this,except for the Enderman Cell,below. Because Endermen have 40 HP,and the Mob Masher cannot deal 40 HP in a single blow,I was forced to use a Mob Crusher,instead. As a direct result,there are only a few Vector Plates around the periphery of the Enderman Cell.
Here's a Darkroom,with a floor made of Cursed Soil. Lights on,of course. The Enderman Cell has the Vector Plates placed exactly like the Darkrooms. As you can see,Vanilla Redstone Lamps provide controllable illumination for the Darkrooms. Each Darkroom is placed above a Cell. Darkrooms have a singular purpose; The production of Liquid Essence for the Cell below. Any items dropped by the mobs that spawn in these rooms are voided,with the Liquid Essence pumped out and below. Each such system has a reservoir in the form of three Reinforced Portable Tanks between the Mob Crusher and the Mob Duplicator,just in case. However,testing has demonstrated that one Mob Duplicator burns Essence faster than one such Darkroom can produce. Which is fine by me. The Lever which controls the lighting is,once again,to my right.
Here's a view of the technical side of the Helvault. The Ender Chests are all the same channel,with an Ender Hopper mounted to the side to collect drops through the wall. By pure chance,they cannot reach into the surrounding Darkrooms,which is nice. As you can see,I'm using Immersive Engineering's High Voltage energy infrastructure for this build; I'll never have all of the chambers going at once,as I don't have the item throughput to make it happen,so I don't need to worry about runaway power consumption. However,when I step away from the Helvault,or even just travel up to a higher floor,mobs will naturally spawn within the Cells,and will then be killed. These mobs almost always have undesirable drops,so I rigged up an ad-hoc disposal system that can expand for as many Ender Chests I have on the Helvault. I locate the items that I don't want that exist within the chests,then stick them into a Whitelist filter on these Enderium Servos. After that,they punt the items into the Trash Cans. Good riddance. Oh,and the red spots you see are Redstone Blocks,chiselled into the Twisted texture. This is so the Mob Mashers can run,and I don't plan on turning them off. They ARE exceptionally dangerous though,as Direwolf can attest to. However,a player without speed buffs can sprint fast enough to travel against green Vector Plates,so I'm relatively safe if I ever need to go into a Cell in order to kill a couple Baby Zombies and/or their Chicken steeds.
Suffer not the Alien,the Mutant,the Heretic. The Inquisition is watchful. Praise be to the God-Emperor of Mankind,and be ever-fearful of His Holy Inquisition.

Warhammer 40k jokes aside,this started as a simple circuit map for my Darkroom lighting controls. However,it looks like a SPANKIN' sigil,so I've decided to adopt it as my personal icon for this world. Looks pretty spiffy,don't you think? Also,down below,you can see my Biodiesel factory,and beside that,my machine house,where the lion's share of my machines are.
